The late,great Rick Hocking on the first TZ750 Dirt Tracker. Champion built this first one and their throttle jockey Hocking rode it on Ascot's sticky clay well enough to create enough interest from other racers to start building a Roller Kit. Steve Baker, Randy Cleek, Skip Aksland built and rode them as well as the Yamaha Factory. It took Roberts to manhandle one to victory at Indy to get the H.D. favoring AMA to ban the beast,pronto.
